Senhal: Elementauswahl und Anmerkungen für KI-Coding-Agenten

Element im eigenen Browser anklicken: geprüfter CSS-Selektor, Screenshot, Notizen. Auf Platte für Claude Code, Codex, Cursor.

Point at what you mean, instead of describing it. Senhal turns a web page into something your coding agent can actually act on. Draw on the page, pick the elements you are talking about, then hand the whole thing over in one gesture. Works with Claude Code, Codex, Cursor, Cline, Aider — anything that can read a folder on your disk. HOW IT WORKS 1. Open Senhal on any page with the toolbar button or a keyboard shortcut. 2. Draw arrows, boxes and freehand marks. Add notes. Highlight a sentence and it is quoted for you. 3. Click the elements you are referring to. Each one gets a number and a CSS selector. 4. Press Agent. Senhal writes the session to your Downloads folder and copies a single paste for your agent's prompt. WHAT YOUR AGENT RECEIVES • A CSS selector for every element you picked, checked for uniqueness on the page — not a guessed one. Senhal prefers a stable identifying attribute (id, data-testid, name, href, aria-label) and only walks up the tree when it has to, so the selector survives a sibling being inserted next to it. • The annotated screenshot, plus one close-up per selected element. • prompt.md: your notes, the quoted text, and the numbered list of everything you marked. • A folder path your agent can open directly — including the /mnt/c/... form when you work in WSL. No more "the button under the third card, on the right" followed by three rounds of the agent editing the wrong component. NOTHING LEAVES YOUR MACHINE Senhal has no network code at all. No account, no server, no telemetry, no analytics. It reads a page only after you open it on that page, and it writes only to your own Downloads folder. The source is shipped readable and unminified so you can check this yourself. ALSO • Interface in English, French, Spanish and German. • Every in-page shortcut can be remapped. • Vertical or horizontal toolbar, light or dark, remembered between sessions. Requires Chrome 111 or later.
